Item Description
As you track your vehicle and experience tremendous lateral G-forces while entering and exiting turns, your suspension geometry changes; this much is common knowledge, but is often misunderstood. As your car experiences sideways forces, the upper and lower control arms change angles in relation to one another. Most people understand this part of the concept, and that the resulting change could pivot the centerline of the affected wheel in such a way as to produce a significant change in camber, resulting in less tire contact with the ground and, subsequently, poor traction and stability. What’s not understood is that simply “dialing in” negative camber to counteract these effects is a patch fix that doesn’t address the changing of the suspension geometry; it merely compensates for it. The trade off then becomes less predictable handling during turns and loss of straight-line stability due to unnecessarily increased camber, not to mention avoidable premature tire wear. This problem is aggravated when the camber is changed by adjusting the angle at the upper control arm; the angles between the upper and lower control arms help determine a vehicle’s roll center, and, where the roll center occurs in each side of the suspension.
To counteract this problem, SSR Front Roll Center Adjuster, an adjustable ball joint that connects to the lower control arm, not the upper, thereby allowing a more correct and apt suspension geometry between upper and lower control arms to be maintained; this insures a more predictable roll center, especially when used in conjunction with an upper control arm camber adjustment kit. The roll center adjuster is an essential part of any tuned suspension on a street or track vehicle lowered 2 inches or more. Vehicles equipped with adjustable upper control arms or camber plates should consider these necessity.
